Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a catalyst filtration device suitable for the synthesis of acetamiprid. Background Technology

[0002] Clothiamethoxam is an aryloxyphenoxypropionic acid herbicide that can be applied to stems and leaves. Clothiamethoxam formulations containing quinacrine detoxifiers are typically microemulsions. During its synthesis, solid catalysts such as metal oxides or molecular sieves are often used to promote the reaction. After the reaction is complete, the catalyst needs to be filtered from the reaction solution using filtration equipment for recycling.

[0003] A search revealed, for example, a utility model with publication number CN220836587U, which discloses a solid catalyst filtration device, including a housing. A control panel is fixedly connected to one side of the housing, and a collection hopper is fixedly installed at the top of the housing. A pair of rotating rods are rotatably connected to the bottom of the collection hopper, and baffles are fixedly connected to the pair of rotating rods. This utility model uses the operation of a drive motor to vibrate the filter screen, thereby filtering the catalyst. During the filtration process, catalyst particles rub and collide with the surface of the filter screen. Over time, this can lead to scratches, pits, or even perforations on the surface of the filter screen, requiring replacement. However, this utility model makes it inconvenient to quickly replace the filter screen when it is damaged, which can easily affect the filtration efficiency. Furthermore, this utility model uses a single filter screen to filter the catalyst, making it inconvenient to perform both "coarse filtration" and "fine filtration" of the catalyst simultaneously. When both "coarse filtration" and "fine filtration" of the catalyst are required, multiple single-layer filters need to be connected in series, which is cumbersome. Therefore, to solve the above defects, the inventors propose a catalyst filtration device suitable for the synthesis of acetamiprid. Utility Model Content

[0004] The main purpose of this invention is to provide a catalyst filtration device suitable for the synthesis of acetamiprid, which can effectively solve the problems in the prior art where it is inconvenient to quickly replace the filter screen and to simultaneously perform "coarse filtration" and "fine filtration" of the catalyst.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A catalyst filtration device suitable for the synthesis of clodinafop-propargyl includes a cylinder, a feed pipe on the top surface of the cylinder and a discharge pipe on the bottom surface of the cylinder. The cylinder has three mounting frames inside, and each of the three mounting frames has a filter plate for filtering the catalyst for the synthesis of clodinafop-propargyl. Insert blocks are fixedly installed on both sides inside the mounting frames, and each of the two insert blocks has a telescopic hole inside.

[0007] A second spring is fixedly installed inside each of the two telescopic holes, and a limit rod is slidably connected inside each of the two telescopic holes. The two second springs are fixedly connected to the two limit rods respectively. Slots are provided on both sides of the filter plate, and limit holes are provided inside each of the two slots. Connecting components are provided on both sides of the inside of the cylinder.

[0008] Preferably, a guide hole is provided on one side of the outer surface of each of the two telescopic holes, and a lever is fixedly installed on one side of the outer surface of each of the two limiting rods, with the two levers passing through the two guide holes and extending to the outside of the two telescopic holes respectively.

[0009] Preferably, the connecting assembly includes three fixing blocks fixedly installed on one side inside the cylinder. The top surfaces of the three fixing blocks are slidably connected to a connecting rod, and the three mounting frames are fixedly connected to two connecting rods. The bottom surfaces of the three fixing blocks are fixedly installed with first springs, and the three first springs are sleeved on the outer ends of the connecting rods and fixedly connected to the top surfaces of the three mounting frames respectively.

[0010] Preferably, the cylinder is rotatably connected to a rotating shaft, and the three mounting frames are all located above the rotating shaft. Eccentric wheels are fixedly installed on both sides of the outer surface of the rotating shaft, and two eccentric wheels are in contact with the bottom surface of the lowest mounting frame.

[0011] Preferably, a motor is fixedly installed on one side of the outer surface of the cylinder, and the output shaft of the motor extends into the interior of the cylinder and is fixedly connected to the rotating shaft.

[0012] Preferably, three processing ports are provided on one side of the outer surface of the cylinder, and the three processing ports correspond one-to-one with three filter plates. Six baffles are fixedly installed on the outer surface of the cylinder on one side of the processing ports, and the six baffles are in pairs, with the six baffles in pairs located on the left and right sides of the three processing ports respectively.

[0013] Preferably, each of the three processing ports is provided with a sealing block inside, and the outer surface of the sealing block is covered with a rubber gasket.

[0014] Preferably, the sealing block has movable grooves on both sides, and baffles are rotatably connected inside the two movable grooves. Two torsion springs are fixedly installed on both sides inside the two movable grooves, and the four torsion springs are fixedly connected to the two baffles respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model discloses a catalyst filtration device suitable for the synthesis of clodinafop-propargyl, which, by setting up three mounting frames and three filter plates, enables the following in practical operation:

[0017] 1. Pull the sealing block out of the treatment port to expose the treatment port. The operator can then insert their arm into the cylinder through the treatment port and push the two levers to move them away from each other. This will pull the limiting rod out of the limiting hole of the filter plate, allowing the filter plate to be pulled out of the mounting frame. Insert the new filter plate into the mounting frame through the treatment port to complete the quick replacement of the filter plate, effectively avoiding the impact on filtration efficiency due to slow filter plate replacement.

[0018] 2. The motor drives the shaft to rotate, which in turn causes the two eccentric wheels to rotate. As the eccentric wheels rotate and the elasticity of the first spring is combined, the three filter plates can move up and down simultaneously, causing the reaction liquid on the three filter plates to shake, thereby filtering out the solid catalyst in the reaction liquid. By passing through three filter plates with different pore sizes, it is convenient to simultaneously perform "coarse filtration" and "fine filtration" of the catalyst. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] This utility model discloses a catalyst filtration device suitable for the synthesis of acetamiprid, such as... Figure 1-10 As shown, the device includes a cylinder 1, a feed pipe 3 located on the top surface of the cylinder 1, and a discharge pipe 4 located on the bottom surface of the cylinder 1. The reaction liquid containing the solid catalyst is poured into the cylinder 1 through the feed pipe 3 for filtration. The filtered reaction liquid can be discharged through the discharge pipe 4, while the solid catalyst in the reaction liquid is trapped inside the cylinder 1.

[0032] The cylinder 1 has three mounting frames 206 inside, and each of the three mounting frames 206 has a filter plate 207 for filtering the catalyst for the synthesis of acetamiprid. The three filter plates 207 are arranged at equal intervals from top to bottom, and the pore size of the three filter plates 207 decreases from top to bottom, so that the reaction liquid containing the solid catalyst can be coarsely filtered and finely filtered at the same time. Insert blocks 209 are fixedly installed on both sides of the inside of the mounting frame 206, and each of the two insert blocks 209 has a telescopic hole 2021.

[0033] The reaction liquid containing the solid catalyst is poured into the cylinder 1 through the feed pipe 3 by an external device for filtration. The solid catalyst in the reaction liquid is trapped inside the cylinder 1. The filtered reaction liquid is discharged through the discharge pipe 4, thus completing the filtration of the catalyst.

[0034] A second spring 2022 is fixedly installed inside each of the two telescopic holes 2021. A limit rod 2023 is slidably connected inside each of the two telescopic holes 2021, and the two second springs 2022 are fixedly connected to the two limit rods 2023 respectively. Slots 208 are provided on both sides of the filter plate 207, and limit holes 210 are provided inside each of the two slots 208. Connecting components are provided on both sides of the inside of the cylinder 1. When the insert block 209 is inserted into the slot 208, the filter plate 207 can be inserted into the mounting frame 206. When the limit hole 210 moves to the position of the limit rod 2023, the second spring 2022 can push the limit rod 2023 to move, so that it is inserted into the limit rod 2023, thereby fixing the filter plate 207 inserted into the mounting frame 206.

[0035] Guide holes 2024 are provided on one side of the outer surface of the two telescopic holes 2021, and paddle blocks 2025 are fixedly installed on one side of the outer surface of the two limiting rods 2023. The two paddle blocks 2025 pass through the two guide holes 2024 and extend to the outside of the two telescopic holes 2021. The operator can manually push the paddle blocks 2025 to move the limiting rods 2023.

[0036] The operator manually pushes the two levers 2025 to move them away from each other, and the two limit rods 2023 can be pulled out from the inside of the two limit holes 210, so that the filter plate 207 can be pulled out from the inside of the mounting frame 206 for replacement.

[0037] The connecting assembly includes three fixing blocks 203 fixedly installed on one side inside the cylinder 1, with the three fixing blocks 203 arranged at equal intervals from top to bottom.

[0038] The top surfaces of the three fixed blocks 203 are slidably connected to the connecting rods 204. The connecting rods 204 can slide up and down on the three fixed blocks 203, and the three mounting frames 206 are fixedly connected to two connecting rods 204. When one of the mounting frames 206 moves up and down, the other two mounting frames 206 will rise and fall accordingly through the connecting rods 204.

[0039] The bottom surfaces of the three fixed blocks 203 are all fixedly installed with first springs 205, and the three first springs 205 are all sleeved on the outer end of the connecting rod 204 and fixedly connected to the top surface of the three mounting frames 206 respectively. When the three mounting frames 206 rise, they will squeeze the three first springs 205 respectively.

[0040] The cylinder 1 is rotatably connected to a rotating shaft 202, and three mounting frames 206 are all located above the rotating shaft 202. Eccentric wheels 201 are fixedly installed on both sides of the outer surface of the rotating shaft 202, and two eccentric wheels 201 are in contact with the bottom surface of the lowest mounting frame 206. A motor 2 is fixedly installed on one side of the outer surface of the cylinder 1. The output shaft of the motor 2 extends into the interior of the cylinder 1 and is fixedly connected to the rotating shaft 202. The motor 2 is powered by an external power source.

[0041] When motor 2 starts, it drives shaft 202 to rotate, which in turn causes the two eccentric wheels 201 to rotate. The eccentric wheels 201 rotate from the lowest point to the highest point, and their contact points push the mounting frame 206 located below upwards. The spring is compressed, and the mounting frame 206 gains an upward displacement. The eccentric wheels 201 continue to rotate from the highest point to the lowest point. The driving force disappears, and the elastic force generated by the deformation of the spring pushes the mounting frame 206 downwards. At the same time, the spring gradually recovers until the eccentric wheels 201 return to the initial position, completing one reciprocating cycle. As motor 2 drives shaft 202 to rotate, the three mounting frames 206 drive the three filter plates 207 to move up and down simultaneously, causing the reaction liquid falling on the three filter plates 207 to shake and filter it.

[0042] Three processing ports 101 are provided on one side of the outer surface of the cylinder 1, and the three processing ports 101 correspond one-to-one with the three filter plates 207. After the processing ports 101 are exposed, the staff can put their hands into the cylinder 1 through the processing ports 101 to disassemble the filter plates 207 or remove the solid catalyst intercepted on the filter plates 207.

[0043] Six baffles 102 are fixedly installed on one side of the processing port 101 on the outer surface of the cylinder 1. The six baffles 102 are arranged in pairs, and the six baffles 102 in pairs are located on the left and right sides of the three processing ports 101 respectively.

[0044] Each of the three processing ports 101 is equipped with a sealing block 103. The outer surface of the sealing block 103 is covered with a rubber gasket. When the sealing block 103 is inserted into the processing port 101, the rubber gasket will deform, thereby improving the sealing effect between the outer surface of the sealing block 103 and the inner wall of the processing port 101, and preventing the reaction liquid from leaking out of the processing port 101.

[0045] Both sides of the sealing block 103 are provided with movable grooves 1032, and baffles 1031 are rotatably connected inside the two movable grooves 1032. Two torsion springs 1033 are fixedly installed on both sides inside the two movable grooves 1032, and the four torsion springs 1033 are respectively fixedly connected to the two baffles 1031.

[0046] The staff first pushes the two baffles 1031 to rotate them to a vertical position. Then, the sealing block 103 is inserted into the processing port 101. After insertion, the two baffles 1031 are released, and the four torsion springs 1033 will reset the two baffles 1031. Then, the two baffles 1031 can be inserted into the two retainers 102 to complete the installation of the sealing block 103.

[0047] The working principle of this utility model is as follows: The operator first powers on the motor 2 and starts the motor 2, so that the motor 2 drives the rotating shaft 202 to rotate. Then, the two eccentric wheels 201 can cooperate with the three first springs 205 to make the three mounting frames 206 and the three filter plates 207 move up and down. Then, the reaction liquid containing solid catalyst is poured into the cylinder 1 through the feed pipe 3. The reaction liquid will fall onto the three filter plates 207 in sequence. With the reciprocating movement of the three filter plates 207, the reaction liquid is filtered. The filtered reaction liquid will be discharged through the discharge pipe 4.

[0048] When the filter needs to be disassembled, the operator first pushes the two baffles 1031 to rotate, so that the two baffles 1031 rotate to a vertical position, so that the two baffles 1031 are pulled out from the two baffles 102. Then the sealing block 103 can be pulled out from the treatment port 101, so that the treatment port 101 is exposed. The operator puts his arm into the cylinder 1 through the treatment port 101 and pushes the two levers 2025 to move them away from each other. Then the limiting rod 2023 can be pulled out from the limiting hole 210 of the filter plate 207. Then the filter plate 207 can be pulled out from the inside of the mounting frame 206. The new filter plate 207 is inserted into the mounting frame 206 through the treatment port 101, and the replacement of the filter plate 207 is completed.
